This card is BUSTED. I laugh at people which don't realize it's potential. Vs priest you can even control the attack value, for example cast one spell to make it 4/6. They just can't deal with it without board, even dragonfire potion won't kill it and next turn they just die, Or take like 12 - 20 dmg.

This is my second game in casual while testing this utterly underestimated card:

This card is insane in miracle rogue, with Tomb Pillager and Counterfeit Coin you can push this out at/or before turn 5 and Conceal. There are very few ways to get rid of this too due to the 6 health. It also has good synergy with Gadgetzan Auctioneer on the following turn since having spare coins and Preparation will often allow for big draws already on the turn Gadgetzan Auctioneer is played. enabling a potential 15+ attack wyrm to face.

If you let it get to that situation, you'd have been equally fucked if it was an Edwin VanCleef or a Questing Adventurer or even just two free Arcane Giants who were stealthed instead. Making an exaggerated situation in which this card is OP doesn't mean this card is OP. It's actually a little too expensive imo.
